This process describes the steps to execute in order to release a new version of SimPy.
Close all tickets for the next version.
Update the minium required versions of dependencies in
setup.py. Update the exact version of all entries in
Run tox from the project root. All tests for all supported versions must pass:
$ tox [...] ________ summary ________ py27: commands succeeded py32: commands succeeded py33: commands succeeded pypy: commands succeeded congratulations :)
Tox will use the
requirements.txtto setup the venvs, so make sure you’ve updated it!
Build the docs (HTML is enough). Make sure there are no errors and undefined references.
$ cd docs/ $ make clean html $ cd ..
Check if all authors are listed in
Update the change logs (
docs/about/history.rst). Only keep changes for the current major release in
CHANGES.txtand reference the history page from there.
Commit all changes:
$ hg ci -m 'Updated change log for the upcoming release.'
Update the version number in
$ hg ci -m 'Bump version from x.y.z to a.b.c'
Do not yet tag and push the changes so that you can safely do a rollback if one of the next step fails and you need change something!
Write a draft for the announcement mail with a list of changes, acknowledgements and installation instructions. Everyone in the team should agree with it.
Build and release¶
Test the release process. Build a source distribution and a wheel package and test them:
$ python setup.py sdist bdist_wheel $ ls dist/ simpy-a.b.c-py2.py3-none-any.whl simpy-a.b.c.tar.gz
Try installing them:
$ rm -rf /tmp/simpy-sdist # ensure clean state if ran repeatedly $ virtualenv /tmp/simpy-sdist $ /tmp/simpy-sdist/bin/pip install dist/simpy-a.b.c.tar.gz
$ rm -rf /tmp/simpy-wheel # ensure clean state if ran repeatedly $ virtualenv /tmp/simpy-wheel $ /tmp/simpy-wheel/bin/pip install dist/simpy-a.b.c-py2.py3-none-any.whl
Create or check your accounts for the test server <https://testpypi.python.org/pypi> and PyPI. Update your
~/.pypircwith your current credentials:
[distutils] index-servers = pypi test [test] repository = https://testpypi.python.org/pypi username = <your test user name goes here> password = <your test password goes here> [pypi] repository = http://pypi.python.org/pypi username = <your production user name goes here> password = <your production password goes here>
Upload the distributions for the new version to the test server and test the installation again:
$ twine upload -r test dist/simpy*a.b.c* $ pip install -i https://testpypi.python.org/pypi simpy
Check if the package is displayed correctly: https://testpypi.python.org/pypi/simpy
Finally upload the package to PyPI and test its installation one last time:
$ twine upload -r pypi dist/simpy*a.b.c* $ pip install -U simpy
Check if the package is displayed correctly: https://pypi.python.org/pypi/simpy
Push your changes:
$ hg tag a.b.c $ hg push ssh://firstname.lastname@example.org/simpy/simpy
Activate the documentation build for the new version.
Send the prepared email to the mailing list and post it on Google+.
